COMBINED LEVEL AND PLUMB.

Specication of Letters Patent.

Patented Sept. 10, 1907.

Application ned June 1, '1907. serial No. 376,805.

To all 'whom 'it may concern:

Be it known that I, JASPER N. WALKER, a citizen of the United States,residing at Marion, in the county of Williamson and State of Illinois,have invented ce1'- tain new and useful Improvements in a Combined Leveland Plumb; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to combination level and plumb for various usesadapted by those oi the trade, and has for its object an inexpensiveinstrument of this character which can easily and quickly be read fromeither side, and one wherein the leveling and plumb members can in nopossible way become unadjusted.

A further object is to provide a means whereby the quick stopping of theneedle may be effected.

With these and other objects in view, my invention comprises the novelfeatures of construction and combinations of parts more fully described,and pointed out in the claims.

In the accompanying drawingsg-Figure l is a side elevation of mycombination instrument. Fig. 2 is a longitudinal section of the same.

Referring now to the drawings forming a part of this specification, ldesignates the beam of the instrument which is cut away at its sides toform recesses to receive plates of glass 2 and 3, which are cemented orotherwise secured therein. tirely through the beam which communicateswith a similar elongated opening 5, and in this opening is mounted theworking parts of my plumb. Adjacent the opening 5 a circular opening 6is cut to receive the working parts of my level.

7 and 8 represent bearing plates which are countersunk into the sides ofthe beam l and are securely held by screws 9. These plates have centralalining perforations to receive the reduced ends of the spindle l0 of anindicator through which passes the wire Il on one end of which is theindexing needle l2 and the other the pendulum I3.

In the opening 4 I have mounted a iiat spring, one end l5 of which issecurely held against lateral movement while the other end 16 bearsagainst the periphery of the spindle 10 thereby causing the quickstopping of the indicator.

l7-17 are gage wires which are inserted in the beam l of the instrumentat one end of the elongated opening 5 and in a direct vertical line fromthe axis of the indicator. When this instrument is used as a plumb, itmay be seen that when it is true, through the action of the pendulum theindexing needle 12 will be directly between the gage wires 17.

A circular opening 4 is cut en In order that the instrument may be usedas a level, I mount a somewhat similar arrangement in the circularopening 6, as that just previously described.

Mounted in the bearing plates 18 and 19 which are countersunk in thebeam l and held by screws 20, is a spindle 2l, the reduced ends of whichare held in central alining perforations in the bearing plates 18 and19. 4Through the spindle 2l, passes a shorter wire than the onepreviously described, on one end of which is the indicating needle 22and on the other end the pendulum 23. I have provided for a doublereading of this level, and when it is used from either side the indexinglinger 22 will register with gage wires 24 or 25, which are mounted inthe beam l and in a line at right angles to the leveling edges.

In using the instrument as a plumb, one end of the beam is brought intoplay for determining the plumb of the wall it being observed that anyvariations will quickly be shown by the indicator not registering withthe gage wires. The friction caused by the spring bearing on theperiphery of the spindle oi the indicator will quickly cause the same tocome to a stop thereby getting a quick result which can be'read fromeither side.

When the instrument is used as level, the operation is essentially asthat described, and any deections may be quickly determined.

It will of course be understood that I do not limit myself to the exactconstruction shown and any variations from the speciiic construction maybe altered without departing from the spirit of my invention.

By the arrangement of the instrument above described, it may be readilyseen that I have provided an instrument that is in no way`complicatedand one that can be manufactured cheap, and that is accurate and can beeasily read and in no way effected by the condition of the weather.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:-

1. In a combined level and plumb, the combination of a beam, glasspanels for the same, a pendulum provided with an indicating needle, apair of gage wires cooperating with said indicating needle, a pair ofbearing plates for supportingl said pendulum, a second pendulumconstituting a level and also provided with an indicating needle, andgage wires 24 and 25 cooperating with the indicating needle of saidsecond pendulum whereby a double reading of said level is provided, andthe Whole is adapted for either a plumb or a level, substantially asdescribed.

2. In a combined level and plumb, the combination of a beam, providedwith a circular and an elongated opening, glasspanels for the same, apendulum located in said openings and provided with an indicatingneedle, a pair of gage Wires located in said elongated opening andcoperating with said indicating needle, a pair of bearing plates forsupporting said pendulum, said beam also provided with a second circularopening, a second pendulum constituting a level mounted in said secondopening and provided with an indicating needle, a pair of platessupporting said second pendulum, and gage wires in said second circularopening at opposite sides of the said beam and coperatng with theindicating needle of said second pendulum, whereby a double reading ofsaid level is provided, and the whole is adapted for either a plumb or alevel, substantially as described.

3. In a combined level and plumb, the combination of a beam, providedwith leveling or plumb edges, and a circular and an elongated opening,glass panels for the same, a pendulum provided with an indicating needlelocated in the said openings, a pair ofgage wires located in saidelongated openings and cooperating with said indicating needle, a pairof bearing plates for supporting said pendulum, said beam also providedwith a second circular opening, a second pendulum constituting a levelmounted in said second opening and provided with an indicating needle, apair of plates supporting said second pendulum, and gage wires 24 and 25located at right angles to the said leveling edges whereby a doublereading of said level is provided and the whole is adapted for either aplumb or a level, substantially as described.

4. In a combined level and plumb, the combination of a beam, providedwith leveling or plumb edges, and a circular and an elongated openingextending transversely therethrough and communicating with each other,glass panels for the same, a pendulum provided with a spindle, and anindicating needle, said pendulum and said needle located in saidopenings, a spring, one end of which is securely held in the circularopening and the other or free end of which bears against the peripheryof said spindle and thereby frictionally retards the swinging of saidpendulum and causes the same to come to a stop and to perform itsfunctions more quickly than it would otherwise do, a pair of gage wireslocated in said elongated opening and coperating with said indicatingneedle,` a pair of bearing plates for supporting said pendulum, saidbeam also provided with a second circular opening, a second pendulumconstituting a level mounted in said second opening and provided with anindicating needle, a pair of plates supporting said second pendulum, andgage wires 24 and 25 located at right angles to the said leveling edges,whereby a double reading of said level is provided and the whole isadapted for either a plumb or a level, substantially as described.
